Stamping, Marking, or Numbering Machines, of whiclrthe following is a specification, reference being had therein to the accompanying drawings. f

Myv present improvement in stamping,

marking, or numbering machines has reference to the printing-heads thereof.

It consists in novel means for holding a name-plate or the like detachably in workingv position upon a printing-head.

My improved means ofidetachably holding a name-plate or the like in working position upon the printing head inA a stamping, marking, or numbering machine s designed, more especially, to enable such plate to be employed whenv required, and to be removed Vwhen not desired to be used, and facilitates the substitution of one'plate for another at will.

Having reference to the drawings, Figure 1 is a front view of a printing-head having an embodiment of my invention applied thereto. Fig. 2 is an end elevation thereof with the operating shaft .of the printing wheels in section. Fig. 3 is afront elevation of the die-carrying Wheel or hub, with one of the diesremoved and shown alongside the said wheel or hub. Fig. 4 is an end elevation of the parts of Fig. 3. Fig. 5 is an end elevation of the movable jaw-member of the name-plate holder. Fig. 6 is a plan viewl of the said movable jaw-member. Fig. 7 is a front elevation of the lsaid movable jaw-member.

. Having reference to the drawings, at 1,v

Fig. 1, is the frame'or housing of a printing-head, which frame for housing will in practice be combined with suitable means for supporting and operating the printinghead. Within the printing-head a set of printingwheels 4, 5, 6, 7,8 and9 is ar ranged. The group of wheels 4 is adapted tol be employedA in printing the case numiber of a lot of shoes. The wheel may be used for printing names or the likeI and the remaining wheels may bel use d for printing sizes and widths. The respective wheels are individually settable to bring the print- Specification of Letters Patent.

ing characters thereof tothe printing line as desired. The particular provisions for setting the same are not material. Various means of setting printing wheels in stamplng, marking and numbering machines are known in practice. It therefore is unnecessary to show or describe such provisions.

Referring to the wheel 5, the said wheel carries dies 5, 5, 5", constituting tradeplates, each bearing appropriate printing characters. In Fig. 3 various names or terms employed in 'the art in connection with shoes appear on the dies. For the reception of the dies, recessed seats 5c, 5c, 5d, are formed upon the wheel 5 at its periphery, in alternation with longitudinally-extending dovetailed ribs 24:', 24:, etc. The dies are formed with beveled lips to fit under the overhanging side-portions of the ribs, as shown in Fig. 4, making the dies themselves partly dovetailed. The die 5b is fittedbetween two ribs 24, 24, which are located at the opposite sides of its seat 5d, its lips being engaged by the over-hanging 'side-portions of such ribs. 1t is inserted or removed by being slid lengthwise between the said ribs. A drawback or disadvantage in connection with a die'held in'place in this -which are tapped radially in the body of the lwheel at the placeswhere the ribs are omitted, and their heads occupy the spaces between the adjacent dies. The said screwheads are accessible at the exterior of the wheel for the purpose of operating the screws. Each screw-head bears by the under side ofits head, which isbeveled, against the inclined sides of the contiguous lips of the dies between which it is situated, thus forcing the other lips of the said dies under the overhanging sides of the adjacent ribs, the screw coperating with the ribs in holding the dies in place. By partially unscrewing one of the screws from its hole in the body of the wheel 5, so as to raise its flanged head from the lips upon the dies with lwhich it co-acts, one or both of such dies may be turned out of the seat or seats therefor and removed, and anotheror others inserted, after which the screw may be tightened up again. This enables the dies to be removed or changed as often as may be required, without any necessity for disassembling the series of .printing-wheels as heretofore. It will be observedlthat each screw 5a engages with a pair of the dies.

The printing wheels of stamping, marking, or numbering machines, are ordinarily made with eleven divisions, ten of which bear numerals or other printing characters, and the eleventh thereof is a blank. There are, accordingly, eleven subdivisions of the Wheel 5, and eleven dies thereon. The means of securing the dies in place, just described, is shown applied in connection with live pairs of such dies, the eleventh die, which is the odd one, being separately held in place in the manner which has been explained.

My means of holding a name-plate detachably in working position upon a printing-head is shown applied to the printinghead invFigs. 1 and 2, and the movable jawmember thereof is shown separately in Figs. 5, 6 and 7. A name-plate 25 is shown in place in Figs. 1 and 2. As is well known, a /plate of this kind, employed in the relations shown, has a central opening within which the peripheral portions of the printing- Wheels work, and through which the typebearing projections pass, as indicated in Fig. .2, While its marginal portions bear lettering or the like to effect a portion of the printing. I employ a fixed jaw 26, Fig. 2,

extending in the direction of the length of j the printing-head, at one side of the portions of the rinting-wheels which are in position to print, and a movable jaw 27 arranged at the opposite side of the said wheels. The two jaws are shaped to engage with the opposite side-edges of the nameplate and hold the same, being grooved longitudinally as at 27, Fig. 5, to receive the iianges 25?, 25a, projecting from the nameplate at the said side-edges. By engagement with such side-edges throughout the length of the name-plate, the jaws keep the name-plate from springing or buckling at any point. At the ends of the name-plate the back of the latterv is kept by the jaws in contact with the lower ends of the sideportions of the housing' or frame 1. The movable jaw 27 is pivotally hung to the said housing or frame, by screws, one of which is represented at 28 in Figs. 1 and 2, fitting holes 28a, Fig. 5, also shown by dotted lines `in Figs. 6 and 7, in ears or lugs 29, 29, which are formed upon the opposite end-portions of the movable jaw-member. A spring is provided in connection with the movable jaw, such spring acting with a tendency to hold the movable jaw closed. Figs. 1 and 2 show an expanding spiral spring 31 employed for the purpose, such spring being confined in the open-topped socket 32 upon one end of the housing or frame 1. An arm 33 extending forward from .the adjacent end of the movable jawem'ember projects over thissocket, and is'acted against by the upper end of a plunger, 34, occupying the upper portion of the socket and pressed upward by spring 31. When it is desired to open the movable jaw to release the plate 23, or permit the latter to be inserted, down- Ward pressure is applied by hand to the` said arm.

Vhat is claimed is 1. Instamping, marking, or numbering machines, the combination with a reciprocating printing-head carrying settable printing-wheels, and a name-plate co-acting with the said printing-wheels in producing the required imprint, of opposite jaws clasp-A ing between them the edges of the said nameplate and thereby supporting it upon said printing-head, said jaws relatively-movable to open and close, and a spring to occasion the closing of the jaws upon the said edges.

2. In stamping, marking, or numbering machines, the combination with a reciproeating printing-head carrying settable printing-wheels, of a, name-plate co-acting with the said printing-wheels in producing the required imprint, a fixed jawv carried by the said reciprocating printing-head at one side of the said printing-wheels grooved to receive and sustain one edge of the nameplate, and a movable spring-actuated jaw upon said printing-head at the oppositeV side of the'said wheelssimilarly grooved tol-receive and sustain the opposite edge of the name-plate.

In testimony whereof I affix my signature in presence of two witnesses.
